Fabricated a new single piece ELT antenna support bracket using the two piece one as a pattern. There are actually still two pieces to the bracket since I don't want to put screws through the arm rest. Instead I made an attach flange what will rivet to the arm rest with flush rivets. The attach flange has nut plates riveted on that will be used the secure the forward end of the main ELT antenna bracket. The aft end will be screwed to the F807 bulkhead.
